MITSUBISHI AY22 Transistor Output Local Unit Module – MELSEC-A Series
When a critical output module fails on the production line, every second of downtime translates directly into lost revenue, missed delivery windows, and cascading equipment faults. The MITSUBISHI AY22 is the transistor output local unit module that keeps your MELSEC-A Series PLC system running without interruption — delivering fast, reliable NPN transistor switching for discrete output control in demanding industrial environments.
Within the MELSEC-A Series family, the AY22 occupies a foundational role as a 16-point NPN transistor output local unit, designed for direct integration with A-Series CPU base units. Its solid-state switching architecture, compact footprint, and proven compatibility with Mitsubishi’s A-Series ecosystem have made it a trusted component in manufacturing plants, process control systems, and machine automation applications worldwide.
